Json format

[kamelEddinee]

I'm working on .net core 3.1 with wpf , is there any way to pass data source as json or class object

Reporting Services only accept "IEnumerable" datas (list of 0 to x objects)

You can convert your json to anonymous type like here : https://stackoverflow.com/a/34324117/5034209
but you should only have in your dataset a x row object

For example :
{ "Id" : 1, "Name" : "MyName" , "City" : { "Name" : "CityName" , "ZipCode" : "0000000"} }
Should be in c#:

new List (){ new { Id = "Name" , Name = "MyName" , City_Name = "CityName", City_ZipCode = "0000000" }

Same thing with class.
